GLEASON, OF WILLOUGHBY, OHIO, ASSIGNOR TO THE GAS MACHINERY ACOM- IPANY, O; E CLEVELAND, OHIO, A CORPORATION OF OHIO CLAMPING `DEVICE FOR COKE-OVEN DOORS Application led July 5,

My invention relates to coke-oven door structures, and particularly to the means for clamping the closure-members or doors of the oven chambers, in place.

5 The object of the invention is to provide clamping means which may be readily and quickly operated and which at the same time will eifect the clamping in an eiiicient manner.

The said invention consists of means hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detail certain means 15 for carrying out my invention, the disclosed means,v however, constituting but lone of the various mechanical formsin which the principle of my invention may be employed.

In the annexed drawings: Figure 1 represents a broken front eleva-V tion of a portion of a coke-oven, showing a door provided with my improved clamping means.

Figure 2 represents a horizontal section ken upon the planes indicated by lines II-II, Fig. 1, and showing the clamping members in their clamping position. Fig. 3 represents a view similar to that of V3b Fig. 2, showing the clamping members in partially released position. f

Fig. 4 represents a view simlia-r to that of Fig. 2, showing the clamping member in a fully released position. Y

Fig. 5 represents a vertical section taken on the planes indicated by lines V-V, Fig. 2. In the oven structure to which the illus? trated embodiment of my invention is applied, the end of the coke-oven chamber 1, Fig, 2, is providedwith a metal frame 2, which is vformed with a rectangular seat or contactA surface 3, entirely surrounding the oven-chamber opening, as shown in dotted lines in Fig. 1, which is engaged by the inner side vof the closure-member 4 to seal such opening, such arrangement being old and well known to those skilled in the art. The frame 2 is secured in place on the oven structure by screws 5 mounted in cross-pieces 6 welded to fixed uprights Y7, such screws en# 1927. Serial No. 203,595.

gaging flanges 8 projecting laterally from I ber such as will-eect the required complete contact between the frame and closure.

Each of these devices, Fig. 5, includes a hor-' izontal bracket 12 secured to the frame by means of nuts 13 and stud bolts 14, and which is formed .with bifurcations 15. The upper bifurcation 15 is formed with a bear-v ing 16 and the lower one with a bearing 17 coaxial with bearing 16. In these bearings is seated a vertical pin 18 formed with a collar 19 resting upon the upper surface of the bracket, and with an eccentric portion 2O which lies between the bifurcations. To the upper end of the pin is xedly secured an arm 21 formed aty its outer end with a :boss 22 having a vertical circular opening 23 therethrough, Fig. 3. VExtending through all of and suitably secured in the openings 23 of the arms 21 which are on one side of the frame and closure-member, is a vertical bar 24, so thatV all of the arms on such side of the frame are connected and may be actuated simultaneously. A similar bar is provided 'for the arms which are on the other side of the frame so that all of these arms are connected and may likewise be actuated simultaneously. Y Mounted on each of the eccentric portions 20 is a swinging angular latch25 whose outer end is provided with a circular opening 26. Extending through all. of and suitably secured in the openings 26 of the latches which are on one side of theframe, is a vertical bar 27, so that all of the latches on such side of the frame are connected and may be simultaneously actuated. A similar bar extends through all of the openings of the latches which are on the other side of the'frame, so that all of such latches are connected and may be actuated simultaneously.

Each latch 25 is provided with an' adjusting screw 28 and the angular form of the latch permits it to be swung around in Vfront of Gil the closure-member 4 so as to bring the screw into a position perpendicular to the face of the closure-member, as shown in Fig. 5.

Each side of said member 4 is provided with fixed lugs 29 corresponding in number with the clamping devices and which may be engaged by the screws 28 as will be further described. K

The operation of the above-described apparatus is as follows Assuming that-the arms 21 and latches 25 have been swung away from the oven-opening and into the position shown in Fig. 4, thereby giving access to the contact surface 3 at the front of the :frame 2, and that the door or closure member 4 has been lifted and placed in contact with .said frame preparatory to clamping it in place, the bars 27 are grasped and pulled over so as initially to swing all of the latches 25 in frontof the door independently of any movement orn the arms 21 or pins 18 or bar 24, asshown in Fig. 3, bringing the screws 28 opposite'but not in contact with the lugs29. The bars 24 are now grasped and pulled ovei` so as .to swing the arms 21 into the position shown in Fig. 2 and hence rotate all of the pins 18 and the eccentrics 20. Such action causes the eccentrics to pull the latches 25 inwardly toward the door and cause the screws 28 to engage the lugs 29 and thus clamp the door against the frame.

The said screws are so adjusted that they will engage the lugs with the required pressure to effect the clamping operation with the necessary security, as' will be understood.

In order to apply the required force for the clamping operation, `one of .each of they sets of arms 21 is provided with lan end socket 30 into which a lever 31 (shown in dotted lines in Figs. 2 to 4 inclusive) may be inserted for this purpose.

The eccentrics 20 are so positioned on the pins 18 that when thearms are in their clamping positions, such eccentrics will lock the arms and latches against inadvertent displacement, by a toggle action, as will be understood.
